April 5 (UPI) -- Netflix is giving a glimpse of the new series The Diplomat.

The Diplomat follows Kate Wyler (Russell), the new U.S. ambassador to the United Kingdom. The character must navigate international crises and her rocky marriage to her husband and fellow diplomat, Hal Wyler (Sewell).

Netflix previously released first-look photos for the series in March.

The Diplomat is created and executive produced by Debora Cahn (Homeland, The West Wing, Grey's Anatomy).

"The Diplomat is a show about the transcendence and torture of a long-term relationships," Cahn previously said. "It's hard to keep a relationship going, be it a marriage or a military alliance. We change, the world changes, and yet we want these relationships to go on forever."

The Diplomat premieres April 20.

The series is Russell's first regular TV role since The Americans.
